Why This Matters for SEO

Schema markup (structured data) unlocks rich results in Google Search — star ratings under products, FAQ dropdowns, breadcrumb trails, and more. Rich results dramatically improve click-through rates and brand visibility. Invalid schema is silently ignored by Google — you won't get rich results even if the markup is present but malformed. This tool catches those invisible errors.

Frequently Asked Questions

What is schema markup?expand_more
Schema markup (also called structured data) is code added to your page (in JSON-LD, Microdata, or RDFa format) that explicitly tells Google what your content is about. For example, schema can tell Google "this is a product with a 4.5-star rating and $29.99 price" or "this is an FAQ with these questions and answers." Google uses this information to display rich results — enhanced search listings with stars, FAQs, prices, and more.
What is JSON-LD?expand_more
JSON-LD (JavaScript Object Notation for Linked Data) is Google's recommended format for structured data. It's added in a <script type="application/ld+json"> tag, usually in the <head> of your page. Unlike Microdata, JSON-LD doesn't require you to modify your existing HTML — it lives separately. This makes it easier to add, maintain, and debug.
Which schema types get rich results in Google?expand_more
Google supports rich results for: Article, Book, Breadcrumb, Course, Dataset, Event, FAQ, How-to, Job Posting, Local Business, Movie, Organization, Product, Recipe, Review, and more. The most impactful for CTR are Product (star ratings, price), FAQ (dropdown questions in results), Review, and Breadcrumb. Not all schema types generate rich results — some just improve Google's understanding of your content.
Why isn't my schema showing as rich results in Google?expand_more
Common reasons schema doesn't generate rich results: (1) JSON syntax errors making the markup unparseable. (2) Missing required fields for that schema type. (3) Schema content doesn't match visible page content (Google requires on-page alignment). (4) Page doesn't have sufficient authority or quality signals. (5) Your schema type isn't eligible for rich results. Use this validator to rule out technical issues first.
